Abstract

PURPOSE: To form a shell form for a short time by placing the inner side of the working part of the 3rd tool by more than the thickness of a shell skirt part on the inner side of the working surface of the 1st tool and placing the working surface of the 4th tool in line with or within the inner side of the working surface of the 3rd tool.
CONSTITUTION: If the 2nd press tool assembly 16 approaches the 1st press tool assembly, the circular working surface 24 formed in the 1st tool and facing the inner side in the radial direction touches the outer side of a skirt part 6 of a shell 2 and inclines the skirt part 6 of the shell 2 to the inner side by the dimension according to a radial dimension x on the circular inner surface 62 of the 3rd tool 52. The free end of the skirt part 6 is let to curve gradually outward and curl outward according to the shape of a circular working cavity 60.
